CURRENT AND VOLTAGE SIMULATION OF AN ORGANIC INVERTER

Pentacene and N,N'-ditridecylperylene-3,4,9,10-tetracarboxylic diimide (PTCDI-C13H27) have been used as organic semiconductors for the fabrication of p-type and n-type organic thin-film transistors (OTFTs). Both types of semi-conductors are well-established and demonstrate good performance in singledevices, but few competitive results have been reported in complementary circuits. In this manuscript, we show the fabrication, electrical characterization and simulation of an organic complementary inverter using pentaceneand PTCDI-C13 as active semiconductors. Simulation was done using a model with physical aspects. The fitting of the parameters of the OTFT model is performed using an optimized parameter extraction technique which is using fuzzy logic to adjust the parameters to its optimal value. We also report good fitting of p-type and n-type parameters for the OTFT model and good results for DC transfer characteristics of the organic complementary inverter. In order to account for the presence of important parasitic elements, we show that the DC characteristics are best simulated using a transient analysis, instead of a DC.
